Knock2
Knock2 identifies website visitors, builds profiles, scores visits, and routes leads into sales workflows. It identifies companies globally, while names and contact details for individuals are available only for US traffic. Profiles can include a visitor’s name, title, verified work email, phone, company, and pages viewed. Its AI lead-scoring agent evaluates visits against a team’s description of its ideal customer profile. Workflows can alert sales representatives in Slack, create CRM records, and enroll visitors in sales sequences. Listed connections include HubSpot, Salesforce, Attio, Slack, Microsoft Teams, Apollo, Outreach, Instantly, Smartlead, Zapier, and webhooks. MCP and REST API access also connects with AI tools such as Claude, Claude Code, Cursor, and ChatGPT. Knock2 is available on web and through an API. Paid plans start at $199 a month, billed monthly, for up to 600 contacts per month and 3,600 credits. A 7-day trial is available; there is no free plan. Monthly credits reset each billing month, and exceeding an allocation requires upgrading or waiting for the reset.
